Caltex C3 synthetic was a 5W-30 that advertised A3/B4, and C3, hanging on the 3.5 HTHS, but have been forced to drop the A3/B4.

shannow, with all due respect, you are linking me to 5w40, and i need 5w30, thats what manufacture required, 5w40 could destroy my engine.(from what i have learned)maybe in Australia the climate is different, otherwise, i have no idea why use 5w40 on 5w30 engine.

btw i need low HTHS, because anything with higher than 3.5 HTHS, is more of "heavy" oil, and could not lubricate my engine properly.(again, from what i have been told)

so i guess ENV c2 is the best for me.

no, no ULSD in israel.

i need low saps oil, because of dpf\catalytic converter.

and the funny\frustrating thing is: OEM doesn't require C1 C2 C3, not in the car manual, but i must have it, or DPF\CC would be damaged.

These things run on just about anything. Yes they have a DPF but do not need a low/mid SAPS oil. As you have stated, Any ACEA B spec will do or API CF (or better) will work too. From memory in a viscosity range of 5w30 to 20w40 is acceptable.

ACEA made C and B specs mutually exclusive in 2010, maybe for good reason. Nowhere does it say you can use ACEA C so I wouldn't.

My pick would be an ACEA B4 in a 5w40 or 0w40. If you want to use 5w30 thats fine. Castrol Edge 5w30 A3/B4 meets that.

I would pick delvac1 LE 5W30. It is lower SAPS but having HTHS over 3.5 it offers greater high temp protection for your long hot summers. P is only 800ppm for catalyst protection. Ash is slightly over prescribed C3levels (1.0 vs. 0.8) but it has very low volatility. My BMW X5 burns zero in 18000 km OCI.It has a higher detergency level than the poor level supplied by C oils.Charlie

That's not very likely to happen. In any event, the requirements you posted are for an A3/B3 A3/B4 type oil, which will have an HTHS of 3.5 or greater. And, if you want to stick with 5w-30, your options are further limited. Do not be going for fuel economy gasoline only engine oils. The Delvac 1 LE 5w-30 already mentioned is about the closest option I can imagine of something reasonably familiar to me.

This engine came out in 2000, based on a much earlier engine....it may now have common rail, but the engine block has been around for a long long time, around 1995. From my experience working at a Mitsi dealership - it'll run forever on anything. I remember the owners manual used to say use any oil better than CD for the 4M41.

first, i want to thank you all, deeply, from my heart, for helping me to do the smart choice, thanks again!

second, i feel like a fool, trying to do the right thing for my car, and even after all the effort, nothing conclusive, only so so.

yesterday i wanted to use valvoline 5w30 ENV C1, but local valvoline branch dosn't sell it.(said no demand for this specific oil, suggest 5w30 XL III.)we have no mobil1 or amsoil importer.(from reading and reading, i would love to get amsoil)

so my option kinda limited.

we have castrol, valvoline, champion, liquid moly, Reinhol, and other oil's, but not wide selection to choose.

my request is this:you guys tell me, 2 3 options, from those brands, and that will be it.

i'm feeling a bit ridiculous, after all the time and effort i spent, on oil.i wish it would have been easy, but, well, its complex.

hope you guys do me this little favor, so i wont bother you or anyone else on the matter.

n0mad - I've been running the Delvac 1 LE 5W30 in my 09 BMW X5 35d for about 25K miles. it hasn't destroyed the engine, and I don't think a 5W40 will do that either.The only real concern is the catalyst (SCR) and DPF. The aforementioned oil has "C" levels of Zn/P and slightly more ash (1.0% vs 0.6-0.8%).

Lmao, 5w40 won't hurt pretty much any 4 stroke engine. What some manufactures call 5w30 is as thick at 100c as most 5w40, its all an illusion. And what the manufacture says to use can have its own agenda, such as fuel economy targets.
